I'm not sure where else this would go, but here seems to be the right place?

My TiVo Premiere XL received some channel updates recently that messed up some channels. In particular in TWC NYC - Channels 647-650 are now updated to MusicChoice channels when in reality it's still the old MGM HD, Smithsonian HD, and other other channel - I think MAV HD. But now the guide reads Music Choice genres for those channels. MusicChoice occupies 601-646 and I notice that some of those are mislabeled too.

Is there a proper channel for this, or can someone in the area also verify this is happening to them too?
